How Color Change Works:It's magic! Seriously, it's the magic of Del Sol's proprietary Spectrachrome® Technology. Spectrachrome crystals reveal their hidden colors when exposed to sunlight. NASA invented it for their space program, and Del Sol enhanced it for everyone under the sun! It's not rocket science, but then again, maybe it is. Learn more here!

WOW Guarantee:All Del Sol products are guaranteed to change colors in the sun for the life of the product, through normal use. Wash and dry it as many times as you'd like! (Follow specific washing instructions on product labels.)
